title: Measurement of slow diffusion coefficients of molecules with arbitrary scalar couplings via long-lived spin states.
abstract: New experiments are described for the determination of very slow diffusion constants by nuclear magnetic resonance (NMR) using long-lived (singlet) states. These experiments are suitable for molecules or conformations featuring a wide range of J-couplings.
